SAFETY RULES

1. STUDY THIS BOOKLET CAREFULLY BEFORE ATTEMPTING

TO OPERATE THIS WRENCH.

2. Never apply more torque than the maximum scale

reading.

3. This torque wrench is designed for manual tightening of

threaded fasteners only. DO NOT USE IT AS A NUT-

BREAKER OR FOR ANY OTHER PURPOSE.

4. Over-torqued or defective fasteners and sockets may

suddenly break. Ratchets that are improperly engaged,

worn out, damaged, or over-torqued may slip or break.

TO PREVENT INJURY, KEEP PROPER FOOTING AND

BALANCE AT ALL TIMES. DO NOT USE THE WRENCH IN

PLACES FROM WHICH YOU MAY FALL OR SLIP, OR

AROUND OPERATING MACHINERY.

5. This wrench will not prevent you from applying more

torque than set, it is not a torque limiting tool. The LCD

display will flash “STOP” if you exceed either the lower or

upper limit of intended use. At low settings the release is

gentle and there usually is no audible ‘click’ signal. Learn

how different amounts of torque ‘feel’, so you will reduce

the possibility of damage and/or injury due to accidental

over-torquing.

6. APPLY FORCE TO THE GRIP ONLY. DO NOT USE ‘CHEATER

BARS’ (a piece of pipe placed over the hand grip).

7. There are no user-serviceable components inside the

wrench. Disassembling the wrench or making any

adjustments will result in the loss of accuracy, and will

void the warranty.

OPERATING INSTRUCTIONS

Before adjusting the wrench to the desired torque setting,

make sure that you are using the correct torque units.

Torque values may be displayed in units of Inch Pounds, Foot

Pounds, Newton Meters, or Centimeter Kilograms.

Your CRAFTSMAN DIGI-CLICK™ Torque Wrench is calibrated

in Foot-Pounds (default on the LCD display) and can be

changed to other units as desired.

WARNING: DO NOT turn the adjusting knob either below the

lowest scale reading or above the highest scale reading. The

LCD display will show torque settings beyond the calibrated

upper and lower limits of your DIGI-CLICK™torque

wrench,these are intended for adjusting purposes only and

are not within the calibrated range.

WARNING: DO NOT use the wrench when batteries are not

installed or when batteries do not have sufficient power to

operate the wrench

TO SET TORQUE

1. Press the red PWR button to turn the wrench on.

2. At initial power up, the LCD display will flash all icons

twice and then show the current torque setting. When

stored or not in use, the wrench should be set to less

than 25% of the maximum capacity.

NOTE: The battery level indicator on the LCD display will

indicate the remaining battery life.

3. Press the gray UNIT button to toggle through desired

units (ft-lb, in-lb, N-m, kg-cm)

4. Pull the adjusting knob out to unlock the adjusting

mechanism.

5. While holding the adjusting knob unlocked, turn it

clockwise to increase the torque, and counterclockwise

to decrease torque. Keep turning until the desired

TARGET torque reading is displayed on the LCD screen.

6. If during a torque setting adjustment the intended

TARGET value is exceeded on the LCD display, the torque

wrench should be first adjusted back to below the

TARGET value, and then back up to the intended TARGET

value.

7. Lock the setting by releasing and, if necessary, pushing

the adjusting knob in. The knob can be turned slightly

back and forth without changing the torque setting to

assure proper engagement of teeth in the locking

mechanism.

8. Press and hold the red PWR button for 2 seconds to turn

the wrench off. This torque wrench has an automatic

shut off feature and will power down after 10 minutes of

non-use.

NOTE: The TARGET torque setting and units will be saved

after shut off. If the torque is adjusted while the power is

off, the correct torque target will be displayed at the power

on screen .

TO APPLY TORQUE

1. Attach the proper socket or other attachment to the

drive. Set the reversing lever of the proper direction of

the operation.

NOTE: If special attachments are used, torque setting must

be corrected in accordance with the directions given below

in the extensions section.

2. Place the socket or attachment onto the fastener to be

torqued.

3. Utilizing the ratcheting head, you may ‘spindown’ the

fastener until resistance is felt.

4. Holding the wrench BY THE GRIP ONLY*, apply SLOW

AND STEADY pull until a momentary release impulse or

‘click’ is felt. Release tightening pressure immediately

when the release is felt.

WARNING: At low torque settings the release is gentle and

there usually is no audible ‘click’ signal. Learn how the

release feels BEFORE you torque to avoid accidental over-

tightening or damage.

*When using long sockets or extensions, the wrench may be

supported at the head (only at the head) with only negligible

effects on accuracy.

5. The wrench resets automatically and is ready for the next

operation.

If during a torque setting adjustment the intended TARGET value is exceeded on the LCD display, the torque wrench should be first adjusted back to below the TARGET value, and then back up to the intended TARGET value. 7. Lock the setting by releasing and, if necessary, pushing the adjusting knob in. The knob can be turned slightly back and forth without changing the torque setting to assure proper engagement of teeth in the locking mechanism. 8.

EXTENSIONS At times, it is impossible or impractical to use regular sockets, (a good example being the tightening of threaded tubing connectors) and a special attachment must be utilized. Such attachments change the calibration of the torque wrench, and it is necessary to calculate the correct settings using the following formulas. NOTE: Regular socket extensions which extend directly under the drive head along the axis of rotation of the ratchet do not affect the calibration of the torque wrench. 4.
